From dust to planets -- II. Effects of wide binary companions and external photoevaporation on planetesimal and embryo formation

Gavin A. L. Coleman

More than half of Solar-type stars are found in binary systems. The numbers of exoplanets within binary systems in s-type orbits now numbers over 700. However, whilst the numbers h…

Formation of multi-planetary systems via pebble accretion in externally photoevaporating discs in stellar clusters

Lin Qiao, Gavin A. L. Coleman, Thomas J. Haworth

In this paper, we investigate how external photo-evaporation influences the formation, dynamical evolution and the resultant planetary architecture of multi-planet systems born in…

Using simultaneous mass accretion and external photoevaporation rates for d203-504 to constrain disc evolution processes

Gavin A. L. Coleman, Thomas J. Haworth, Ilane Schroetter +1

We cannot understand planet formation without understanding disc evolutionary processes. However, there is currently ambiguity about how protoplanetary discs transport angular mome…

How the gradient of versus UV field strength yields insights into the ages of protoplanetary disc populations

Gavin A. L. Coleman, Sierk E. van Terwisga

FUV radiation from massive stars launch photoevaporative winds from the outer regions of protoplanetary discs around other stars, removing gas and dust. Observations have identifie…

Runaway origins of a disc mass gradient in Orionis

Gavin A. L. Coleman, Thomas J. Haworth, Jinyoung Serena Kim

Radiation from massive stars is known to significantly affect the evolution of protoplanetary discs around surrounding stars by driving external photoevaporative winds. Typically m…

Solar C/O ratio in planet-forming gas at 1 au in a highly irradiated disk

Ilane Schroetter, Olivier Berné, Emeric Bron +18

The chemical composition of exoplanets is thought to be influenced by the composition of the disks in which they form. JWST observations have unveiled a variety of species in numer…

The observable impact of runaway OB stars on protoplanetary discs

Gavin A. L. Coleman, Jinyoung Serena Kim, Thomas J. Haworth +2

UV radiation from OB stars can drive ``external'' photoevaporative winds from discs in clusters, that have been shown to be important for disc evolution and planet formation. Howev…

How the microphysical properties of external photoevaporation influence the global evolution of protoplanetary discs

Gavin A. L. Coleman, Thomas J. Haworth, Lin Qiao

External photoevaporation is one of the dominant mechanisms for mass loss from protoplanetary discs. However this mass loss is theoretically expected to depend upon the microphysic…

The past, present and future of observations of externally irradiated disks

Planet formation environments collaboration, Megan Allen, Rossella Anania +51

Recent years have seen a surge of interest in the community studying the effect of ultraviolet radiation environment, predominantly set by OB stars, on protoplanetary disc evolutio…

Photoevaporation obfuscates the distinction between wind and viscous angular momentum transport in protoplanetary discs

Gavin A. L. Coleman, Joseph K. Mroueh, Thomas J. Haworth

How protoplanetary discs evolve remains an unanswered question. Competing theories of viscosity and magnetohydrodynamic disc winds have been put forward as the drivers of angular m…

FRIED v2. A new grid of mass loss rates for externally irradiated protoplanetary discs

Thomas J. Haworth, Gavin A. L. Coleman, Lin Qiao +2

We present a new FRIED grid of mass loss rates for externally far-ultraviolet (FUV) irradiated protoplanetary discs. As a precursor to the new grid, we also explore the microphysic…

A terrestrial planet candidate in a temperate orbit around Proxima Centauri

Guillem Anglada-Escudé, Pedro J. Amado, John Barnes +28

At a distance of 1.295 parsecs, the red-dwarf Proxima Centauri ( Centauri C, GL 551, HIP 70890, or simply Proxima) is the Sun's closest stellar neighbor and one of the best stud…
